most machines have a fused IEC inlet like this


have you checked both fuses - in the plug & mains inlet ?

with the power off you should be able to prove
you have continuity between the L, N & E terminals on the back of the inlet and the 3 pin plug

as the E-stop switch is a single pole mains switch
it should break the live supply from the IEC inlet -
double check the switch is working and it does not switch the neutral as the Chinese have a habit of doing

resistance checks on the double pole on off switch should prove if its working , or not

PS
a possible wiring diagram


note - the E-stop is shown as being after the main ON/OFF switch
it could be before

You nailed it fellas it was the fuse in the mains inlet, i wouldn't have known that was there with a gun to my head.

Appreciate all the input and advice lads, thanks very much

Always satisfying to see someone fix they're problem ;) Good tip on the fuse I didn't know that either but mentally noted.
